Question
Where are the valence electrons of an atom present?
- Near to the nucleus
- Next to the first shell
- Last shell
- Shell behind the outermost shell
Hint:
The valence electrons are present in the last shell which is the valence shell.
The correct answer is: Last shell
- The valence shell is the outermost shell of an atom.
- The electrons in the valence shell are called valence electrons and the electrons in the inner shells are known as core electrons.
- The reactivity and chemical bonding capacity of the atoms are determined by the valence electrons which is present in the last shell.
